Title: Cathode structures
IPC: H01J9/18
Filed: 1973-11-05
Abstract: 1453293 Electron guns RCA CORPORATION 5 Nov 1973 [6 Nov 1972] 51322/73 Heading H1D A method of assembling a cathode 31 and an apertured grid 23 with their confronting surfaces a precise distance S apart, comprises positioning the surfaces a reference distance R apart, moving the cathode and grid towards each other a distance R-S and fixing the cathode and grid together. In an electron gun the method avoids relatively large changes in the screen grid cut off voltage due to arcing between the cathode and control grid caused by variations in S. An electron gun assembly 21 comprises 3 in-line guns 22a, 22b, 22c each with a cathode 31 having an emitting surface 36, control, screen, first and second accelerating and focusing grids 23, 24, 25, 26 with aligned apertures. The electrodes are fixed on two glass rods 27a, 27b. The electrodes are assembled on a "span-set" unit 38 comprising a two part carriage (39) Fig. 2 (not shown) holding assembly 20 without the cathodes, a carriage (40) holding a cathode 31, a measurement probe assembly (41) and a welding assembly (42). Carriage (39) includes front and rear members 47, (48) connected by a vernier adjuster (53). The probe assembly 41 includes distance gauges 81, 82. Gauge 81 comprises a nozzle 83 from which air impinges on a surface 37 of grid 23 and the back pressure varies according to the distance between the nozzle and the surface. The distance between gauge 82 and cathode emitter surface 35 is measured capacitatively. The carriage member 47 and cathode 31 are moved until zero readings are obtained on gauges 81, 82. The member 47 is retracted a known distance, probe assembly 41 is moved, member 47 is moved to its non-retracted position and then moved a distance X-S to accurately position the cathode in the assembly with respect to the grid. The cathode and grid are then welded together by the assembly (42) comprising 4 welding guns arranged radially about the assembly axis 44 and moved pneumatically. The assembly 20 is then moved laterally on a slide (56) to align another gun with the next cathode to be inserted. The span set unit is semi automatic. The cathode may be a dispenser type; the guns may be arranged in a delta.

In the arrangement shown the pedals drive a flywheel 2 mounted in frame 1 and around which is a brake strip 4 the tension of which can be varied by handle 8 adjusting a tensioning pulley 5. One end of the strip 4 is connected to arm 11 which in turn is connected to a spring 29 anchored to the frame 1. The other end of arm 11 is connected to a pendulum arm 15 pivoted at 17 and the arrangement is such that the position of the arm 15 is determined by the tension in the brake strip 4. The lower end of arm 15 is formed with claws 18 holding ball 19 so that the latter is freely rotatable in the claws. The ball 19 is positioned between disc 20 also rotated from the crank-shaft by belt 23 and rotatable cylinder 24 the arrangement being such that the rotational speed of cylinder 24 is proportional to the speed of the crank-shaft (or flywheel) and to the setting of the ball 19 relative to the disc 20 by the arm 15. The output shaft 25 from cylinder 24 is connected to an instrument for indicating or registering the effort and/or the energy delivered by the person using the device. The end 27 of arm 15 can be associated with a scale to give an indication of the brake load. The cylinder 24 may alternatively be provided with a contact 26 and suitable circuitry provided so that it can operate a tachometer. The simple ball and claw device may be replaced by more sophisticated ball and roller devices to cut down the hysteresis effect of the movement of arm 15. Figs. 3, 4 and 5 (not shown).

Title: Shuttleless loom with at least one weft thread carrier
IPC: D03D47/24
Filed: 1976-12-13
Abstract: The weaving machine has a guide (4) for one or more weft-thread grippers (3), which extends through the shed and which forms a continuous path. Arranged at one side end of the shed is a throwing device (6) for the gripper or grippers (3), which comprises a circular portion (16) of the guide (4), in which circular portion rotates a flywheel (15) provided with take-up devices for the gripper or grippers (3).

A sterilizer for fluid media particularly water comprises a casing, a fluid conducting pipe, which is constructed of a material to which impurities e.g. colloidal matter contained in the fluid do not stick thereby prohibiting film build up on the inner surface of the pipe, said pipe having multiple convolutions with adjacent substantially unidirectional elongated portions in substantially parallel relation and a plurality of germicidal lamps mounted in the casing adjacent and parallel to said elongated pipe portions so as to irradiate each pipe portion from at least two directions at least the elongated portions of the pipe and preferably the whole of it being transparent to the germicidal e.g. ultraviolet radiation emitted by the lamps. As shown in Figs. 1 and 3 a casing 10 contains a fluorinated polyethylene pipe 22 which has straight portions 24 and bends 26. The pipe is attached to the top and bottom of the casing 10 by clips 28 and to inlet/outlet 18/20 on the top 16 of the casing. Side 12 of the casing removably fastened to the remainder of the casing by screws 14 supports U/V lamps 30 on bracket 32 such that they are positioned between adjacent pairs of portions 24. This ensures that both sides of the tube are irradiated, and preferably the diameters of the pipe and lamps are selected so that the full cross-section of water in the pipe is effectively penetrated by the U/V radiation. Screened lenses 34 enables the operation of the lamps to be visually monitored. The inner surfaces of the casing may be polished so as to reflect radiation.
